Hi All,

I know this always starts a big disscusion off but what grade oil is ok for a fully standard 2006 2.5 STI. I never drive it hard etc so the normal, every day oil would be good for me, what grade would you use?

Carl

 

a 5W40 synthetic

 

Cheers, so being told had to be a min of 15W 50 isnt true?

 

yes, no need for that grade of oil

 

Why do people say that it must be at least 10 or 15 W if it doesnt need to be?, Or is it people with money to burn lol.
Where in the manual does it say type etc, couldnt find it etc.

Many thanks!

 

10w40 semi synth is the standard oil, 5w40 is normally a fully synthetic as is 15w50, either one can be used but dont go for anything thicker than a 50.

you will nevefr get a straight answer on here. best to check the owners handbook! Thats what its for.

 

the owners handbook doesn't just list a single oil though

there is a range of suitable oils according to Subaru

 

So would you guys say anything from 5W 40 up to 15W 50, semi or fully synthetic is good?

 

I would go with what Rich said, 5w40 fully synthetic

Tony

 

Would any brand of 5w 40 be ok?

 

as long as it's not some random unknown make, go for a known brand, but you don't need to spend a fortune

 

Cheers guys, Ebay here I come lol

 

eBay?

why not go to a local motor factors or Halfords?

 

Halfords I was at today and all they had in was their own and a lot of empty shelves lol

 

there's nothing wrong with Halfords own brand oil

it's actually made by Comma anyway

 

Is it????? They have some good deals on their own stuff!

 

yes, Halfords don't make their own oil

 

lol i thought it might be some unkonown brand. Funny thing is, their own oil at 5w 40 I can get Mobil 1 15w 50 almost same cost, which is best?

 

you need a trade card
